Security Advisory-Information Leakage Vulnerability via MPLS Ping in VRP Platform

  • SA No:Huawei-SA-20140924-01-VRP
  • Initial Release Date: Sep 24, 2014
  • Last Release Date: Oct 16, 2014

VRP (Versatile Routing Platform) has been developed by Huawei to provide improved IP routing services. The VRP has been widely applied to network devices, including high-end and low-end switches and routers, wireless and transmission devices.

Information leakage vulnerability exists in several devices using VRP platform, because the MPLS LSP Ping service is bound to unnecessary interfaces, which can cause the leak of IP addresses of devices (Vulnerability ID: HWPSIRT-2014-0418).

This vulnerability has been assigned a Common Vulnerabilities and Exposures (CVE) ID: CVE-2014-8570.

The vulnerability can cause the leak of IP addresses of devices.

The vulnerability classification has been performed by using the CVSSv2 scoring system (http://www.first.org/cvss/).

Base Score: 5.0 (AV:N/AC:L/Au:N/C:P/I:N/A:N)

Temporal Score: 4.1 (E:F/RL:O/RC:C)


1. Prerequisite:

Attacker can connect to the devices.

2. Attacking procedure:

By sending a series of crafted MPLS LSP Ping packets, it is possible to enumerate the IP addresses allocated to interfaces via reply packets.

In global view, run the undo lspv mpls-lsp-ping echo enable command so that no port replies to the LSPV ping packets.
